will QML work for desktop applications?

view story

http://ubuntuforums.org – I am interested in making applications, and I'm familiar with JavaScript, so QML sounds like a good start. What I want to know is, will applications written in QML work in the Ubuntu desktop? Most of the information I'm getting on QML mentions Ubuntu touch, but I don'tn have a device running Ubuntu touch, so I'd prefer to run it on my laptop. (That being said, is there an emulator for Ubuntu Touch? As I said, I'd prefer to run any apps I write on my laptop, but if one day I decide to write for phones, an emulator would be very handy :) ) (Hardware)
